Carbon dioxide kinetics and capnography during critical care
Greater understanding of the pathophysiology of carbon dioxide kinetics during steady and nonsteady state should improve, we believe, clinical care during intensive care treatment. Capnography and the measurement of end-tidal partial pressure of carbon dioxide (PETCO2) will gradually be augmented by relatively new measurement methodology, including the volume of carbon dioxide exhaled per breat...
متن کاملclinical investigations in critical care Dynamics of Carbon Dioxide Elimination Following Ventilator
set ventilators. Objective: To define and characterize the transient re¬ sponse of VCO2 to a well-defined change in ventilation. Methods: Forty-four patients in stable condition re¬ ceiving volume-controlled mechanical ventilation had trend recordings of ventilator pressures, flow, volumes, Vco2, and end-tidal CO2 (ETCO2) for 20 min. At time t0, the minute ventilation was either increased (n=22...
متن کاملTranscutaneous oxygen and carbon dioxide monitoring in intensive care.
Transcutaneous oxygen (TcPo2) and carbon dioxide (TcPco2) tensions were compared with arterial values in 23 children aged 4 months to 14 years, all requiring some form of respiratory support, but not in shock. Electrodes were placed on the upper chest and were heated to 45 degrees C. For TcPo2 and arterial oxygen (Pao2) a tight linear correlation over the range 6 to 14 kPa was found. Arterial c...
متن کاملCarbon dioxide clearance and deadspace during high frequency jet ventilation. Investigations in the dog.
The effects of frequency, tidal volume and added deadspace on carbon dioxide clearance were measured during high frequency jet ventilation at 1, 3 and 5 Hz in dogs. With a short, small volume deadspace, carbon dioxide clearance increased with minute volume at each frequency, but for a given minute volume the clearance decreased with increase in frequency. At 5 Hz, carbon dioxide clearance was l...
متن کاملCatalytic Cyclocarbonylation in Compressed Carbon Dioxide: Pressure Influence of Carbon Monoxide and Carbon Dioxide
Among the current interests in organic synthesis are those reactions performing multiple C-C bond formation, in special when they undergo under catalytic conditions. Due to its properties, there is a growing interest on the use of compressed fluids (CF) as solvent media in catalytic processes. In this context, we present herein studies that aim to the development of a cleaner technology for the...
